ments in. Unloading, Loading, and'Conveying Apparatus; and we do herebydeclare the following to be a full. clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

This invention relates to improvements in unloading, loading, andconveying appara tus, and pertains more especially to apparatus of thecharacter indicated wherein carriages are mounted upon and movable alonga track and during the travel of a carriage along the said track if thecarriage is unladen the following occurs: First, a rack arranged at anelevation above the track and normally at one' side of the track andcapable of being swung in a horizontal plane to and over the track isswung into position over the track by the operation of mechanismcontrolled by the moving unladen carriage which is to be loaded from therack; second, the rack is antomatically locked upon swinging the rackinto its unloading position over the track;

third, any ware borne by the rack is delivered onto the carriage;fourth, the carriage having been laden renders the means employed inlocking the rack in its unloading position inoperative and permits therack to be swung into its normal position ready to receive-another load,and the laden carriage moves along the track to the desired destina- Theobject of thishinvention is to provide apparatus of the charactervindicated wherein a carriage already laden will pass by the movableware-conveying rack without resulting in the actuation'of the rack; butan unladen carriage will in moving along the track preparatory to itspassage by the rack actuate mechanism operatively connected with therack, and thereby effect the actuation of the rack into its unloadingposition, wherein any ware upon the rack is removed from the rack ontothe carriage by ware-removing members with which the carriage isprovided.

, Another object is to render the apparatus simple and durable inconstruction and reliable in its operation.

With these objects in view this invention consists in certain featuresof construction and combinationsof parts hereinafter described, andpointed out in the claims. i

(lur improved apparatus comprises a suitably-supported endless track T,which is arranged in a horizontal plane at the desired elevation. Thetrack T extends (see Fig. 1) past two racks A and B, from which ware orarticles are to be conveyed to a distant point arranged adjacent anotherportion of the said track. The track T adjacent the last-mentioned pointextends around a sprocket-wheel Pt, operatively mounted on asuitably-supported vertically-arranged shaft H, which is operativelyprovided below the said wheel with a driving-wheel R to which power issuitably applied. The racks A and B are stationary and movable,respectively. The traekT adjacent the stationary rack A extends around asprocket-Wheel R", which is supported in any approved manner. The trackT is provided with suitable bends, if required, as shown at C.

The track T to facilitate the building and any subsequent lengthening,shortening, or change in trend of the same is made in sections 20,assembled endwise, with adjacent track-sections arranged in linelongitudinally, as shown in Figs. 2 and 3. Preferably adjacenttrack-sections 20 are provided at their meeting or adjacent ends withdepending horizontally-arranged ears 22, clamped together in anyapproved manneras, for instance, by a suitably-applied bolt D and nutcl, as shown in Figs. 2, 3, and 4. An endless chain or carrier Roperatively engages the sprocket-Wheels R and R and lies in achannel 2,formed in and centrally widthwise of the track T. The channel 2. extendslongitudinally of the track. The chain R is arranged on edge-that is,with the pivotal connection R between adjacent links of the chainarranged vertically, so as to render the chain readily capable ofpassing around the sprocketwheels. The chain R is guided in any approvedmanner between the Wheels R and F8 --as, for instance, bysuitably-applied sprocket-wheels it, supported from the track T. Theinner portion of the track T is cut away, as at adjacent thesprocket-wheels R and R", as shown in Fig. 1. The track T is provided atthe sides with upwardly-projecting flanges If, which extendlongitudinally of the track and are arranged to form side guides for theWareeonveying carriages 25, mounted upon the track and arranged atsuitable intervals longitudinally of the track, which carriages areattached to the chain E.

To enable adjacent track-sections 20 to participate in mutuallysupporting each other at their adjacent ends and to prevent displacementof each of the said sections at the said ends independently of the otherof the said sections, one of the said sections is provided at each sideof its channel 2 and exteriorly with a vertically-arranged car 28,projecting between two correspondingly-arrangcd cars 24, formed uponthe-other of the said sections,

and the interlocking ears 23' and 24: of the said sections at each sideof the track are also but not necessarily secured together by asuitably-applied bolt 1*] and nut a.

The carriages 25 are obviously propelled by the chain It during theactuation of the chain. Each carriage 25, as shown very clearly in Figs.5, 6, 7, 8, 10, 12, 13, and 14, comprises a body portion 1', which isattached to the chain R in any approved manner and rests upon the trackT at the sides of the channel 3. Each carriage 25 comprises also aplatform u, which is pivotally mounted on the body portion rof thecarriage, being pivoted, as at a, horizontally to and transversely ofthe said body portion. The platform 21 ofeach carriage 25 is arrangedhorizontally upon the body portion '1' of the carriage; but the forwardportion of the platformthat is, the platform forwardly of its axisisweighted, as at 26, (see Figs. 6, 12, 13, and 14,) and willtipdownwardly whenever permitted to do so. The said platform '11 isprovided with several vertically arranged upwardly projecting flanges 11which extend longitudinally of and from end to end of the platform. Thebody portion r of each carriage 25 is provided rearward of but in closeproximity to the rear end of the platform of the carriage with twoupwardly-projecting arms or members 27, ar-' ranged a suitable distanceapart widthwise of the platform. (See Figs. 5, 6, 7, 8, 10, and 12.)

The stationary rack A is arranged in the main over the track T, as shownin Figs. 1, 5, 6, and 7, and the ware-receiving seat a of the said rackis arranged at an elevation at and slightly above the path of theplatforms It of the carriages 25, as shown in Figs. 6 and 7. The seat inis provided with slots 11", which extend from end to end of the seat andare arranged to accommodate the location of the flanges of the platform11 of a carriage 25 during the propulsion of the said carriage along andpast the said seat to receive a piece of ware or article to be unloadedfrom the rack A onto the said platform. The chain R is propelled andactuated in the direction in-* dicated by the arrow marked upon thetrack T, and the rack A at the rear end of the seat a comprises a web (1which connects the different portions of the seat 11 together andpermits of the provision of a seat (1 having the slots (.0

In Figs. 5, 6, and a jar w is shown placed upon the seat a, and acarriage 25 is in position to receive the said jar from the said seat 7that is, Figs. 5, 6, and 7 show the ware-removing arms or members 27 ofthe said carriage in engagement with the said jar. The web rt of therack A is slotted vertically, as at 28, to accommodate the location ofthe arms or members 27 of the carriages 25, and the arms or members 27of the platform nof each carriage 25 are arranged such a distance apartlaterally that during the propulsion of the said carriage they comesimultaneously into engagement with the jar or article 1 to be therebyremoved from the rack A, and thereupon shove the said jar or articlefrom off the seat a of the said rack in the direction in which the saidcarriage is being propelled and result in the delivery of the said wareor article onto the said platform. The rack A is provided at a suitableelevation above the seat (I- with two horizontally-arranged guardformingarms 30, which project in the direction in which ware placed upon thesaid seat is tobe removed from the rack and are located at oppositesides, respectively, of the rack in position to prevent displacement ofware placed upon the rack laterally in opposite directions,respectively. The rack A is provided at the bottom with two arms orbrackets 32, depending from the seat (t at opposite sides, respectively,of the path of the carriages 25, as shown very clearly in Fig. 7, whichbrackets or arms are rigidly secured in any approved manner to the trackT.

The primary object of this invention is not only to convey-ware orarticles from the stationary rack A, but also to convey ware or articlesfrom the movable rack B, arranged at any suitable point between the rackA and the destination of the ware or articles to be conveyed from thesaid racks. The rack B thus arranged intermediately between thestationary rack A and the destination of the ware to be conveyed ismovable into and out of position over the track T. v

The rack B is shown very clearly in Figs. 9, 11, 14, 15, 16, and 17. Therack B substantially corresponds in construction with the stationaryrack A, already described; The rack B has a ware-receiving seat 6, whichis arranged at an elevation at and slightly above the path of theplatforms u of the carriages 25 when the said platforms are laden. Theseat I) is provided with slots Z2 which extend from end to end of theseat and are arranged to accommodate the location of the flanges e ofthe platform a of.a carriage 25 during the propulsion of the saidcarriage along and past the said seat to receive a piece of ware orarticle to be unloaded from the rack B onto the said platform when thesaid rack is in position to deliverthat is, over the track T. The rack Bat the rear end of the seat 6 comprises a web 5, which connects thedifferent portions of the seat 5 together and permits the provision of aseat 7), having slots 6 In Figs. 9, 11, 14:, and 15 a jar w is shownplaced upon a seat 6. In Fig. 9 the rack B is shown in itsware-receiving position. In Figs. 11, 1 t, and 15 the rack B, laden witha jar w, is shown swung into its ware delivering or unloading positionover the track T. In Figs. 8, 10,12, 13, and 14 a carriage 25 isshownapproaching the rack B. In Figs. 16 and 17 a jar w is shown delivered toa carriage 25 from the rack B. Preparafrom the racks, to a tory to theremoval of a jar to from the rack B onto a carriage 25 theware-receiving arms or members 27 of the said carriage come intoengagement with the said jar the same as already described during theremoval of a jar from the stationary rackA. The web 6 of the rack B isslotted vertically, as at 38, to accommodate the location of the arms ormembers 27 of the carriages 25. is provided at a suitable elevationabove the seat 6 with two horizontally-arranged guardforming arms 35,which project in the direction in which ware placed upon the said seatis to be removed from the rack and are located at opposite sides,respectively, of the rack i position to prevent displacement of wareplaced upon the rack laterally in opposite directions, respectively.

\To render practicable the conveying of ware destination in common,the'movement of the movable rack B into its ware delivering or unloadingposition is controlled by a carriage 25-, which is unladen, and acarriage 25, already laden with a jar to or piece of ware deliveredthereon from the sta- The rack B' tionary rack A, moves past the movablerack B without resulting in the actuation of the said movable rack; butacarriage 25, passing to the rack B and not having received a jar w orware from the rack A, shall at the proper time effect the movement ofthe rack B into its unloading position over the track T.

The means employed in effecting the actuation of the rack B into itsware delivering or unloading position comprises (see Figs. 1, 8, 9, 10,11, 13, and 14) an endwise-shiftable bar G, arranged horizontally andexternally of and extending along the track T, which bar has bearing intwo boxes 34, rigid with the track and arranged a suitable distanceapart longitudinally of the track. The bar G is located between theracks A and-B and provided at its outer side and centrally between itsends with a laterally-projecting arm 36, whose outer longitudinal edgehas the trend required to form an incline g, which faces laterally andtoward the rack B. The trend of the incline g is therefore inwardly andtoward the rack B from the outer and free end of the arm 36. The rack Bis arranged a suitable distance forwardly of the forward end of the barG, and a lever H, instrumental in swinging the said rack in a horizontalplane from its outer and ware-receiving position into its inner andunloading position, extends longitudinally of the outer side of the saidbar and is fulcrumed vertically and. centrally between its ends, as at37, to a bracket 39, which is formed upon and projects laterally fromthe track T below the said bar. The movable rack B is secured .at itsweb to the forward end of the lever H. The lever H isprovided at itsrear end with a vertically-arranged roller k, which in the normalposition of the rack B-that is, when the said rack is in itsware-receiving position is arranged in engagement with the inner end ofthe incline g of the bar 6, as shown in Figs. 1, 8, and 9. It isobvious, therefore, that when the bar G is actuated that is, in thedirection of the rack B-the incline g of the said bar will swing thelever H in the direction required to move the rack into its waredelivering or unloading position over the track T. In Figs. 1 and 9 therack B is shown in its ware-receiving position and bears a jar 11 InFigs. 11, 14, and 15 the rack Bis shown in its unloading position overthe rack T. The lever H during its actuation by the incline g movesagainst the action of a suitably-applied weight I, which is shown inFigs. 9, 11, and 14. The weight ll acts, therefore, to retain the rack Bin its normal or ware-receiving position. The weight I is suspended by acable J, which is attached to the forward or rackbearing end of thelever H and leads over a guide-sheave 40, which is supported from an armor bracket 42, which is rigid with and projects laterally from the trackT. The bracket or arm 42 has an upper track-forming surface engaged by aroller 43, with which the forward and rack-bearing end of the lever H isprovided. The bracket or arm 42 is arranged substantially concentricallyof the axis of the lever H, so that the roller 43 will remain inengagement with the track formed by the said arm during the actuation ofthe said lever. A suitably-applied weight K acts to retain the bar G inits rearward and normal position. The weight K is suspended by a cable70, which is attached to the outer or free end of the arm 36 of the barG and leads over a guide-sheave 44, supported from the outer end of anarm or bracket 45, which is rigid with and projects laterally from thetrack T.

The track T is provided adjacent the bar U: and rearwardly of thefulcrum 37 of the lever H and at each side of the channel 25 of thetrack with a depression T, which extends longitudinally of the track,and the poise or downward extension 26 of the forward end of theplatform u of each carriage 25 has the dimensions required to cause theforward portion of the said platform when the platform is unladen to tipdownwardly by gravity into the track depressions T during the passage ofthe said carriage over the said depressions, as shown very clearly inFigs. 8, 10, 12, 13, and 14. The forward end walls T of the depressionsT slope upwardly and forwardly, so as to gradually lift thedownwardly-tipped forward and heavier end of the unladen platform a ofthe carriage during the passage of the carriage from over the saiddepression.

The jar or ware w to be conveyed by a carriage 25 is carried upon therear portion of the platform 11 of the said carriage, and the weight ofthe load upon the rear portion of the laden platform is sufficient toprevent the forward portion of the said platform from tipping downwardlyduring the passage of a laden carriage over the depressed portion of thetrack T.

The bar (f is provided at or near its arm 36 with a rearwardly-facingshoulder 50, (see Figs. 8, 10, 13, and 14,) which shoulder is arrangedto be engaged by a pin or member 52,

which is rigid with and projects laterally from the platform u of anunladen carriage approaching the rack B-that is, the bar (1? is providedwith ashoulder 50, which is arranged in the path of a pin or member 52of the platform a of an approaching carriage 25 when the said platformis unladen. It will be observed, however, as shown in dotted lines, Fig.13, that the pin or member 52 of the platform 11 of the carriage whenthe said plat form has been lifted from the track depression T isarranged high enough to enable the said member 52 to pass over and pastthe bar G, and obviously, therefore, a laden platform will pass over andpast the said bar without coming into engagement with the shoulder 50 ofthe bar.

The forward end walls T of the track depressions T are arrangedforwardly of the shoulder 50 of the bar Ur, and the arrangement of theparts is such, therefore, that the platform n of each carriage 25 whichis unladen will during the passage of the said carriage to and over thetrack depressions T during the propulsion of the carriage tip downwardlyat its forward and heavier end into the said depressions, so as to bringthe pin or project ing member 52 thereof forward of the shoulder 50 andresult in the engagement of the said shoulder by the said pin orprojecting member of the platform, and hence result in the forwardactuation of the bar G against the actuation of the weight Kand in theswinging of the rack B into its ware delivering or unloading positionagainst the action of the weight I. The shoulder 50 is arrangedsubstantially concentrically of the axis of the platform u, so thatupward displacement of the forward and heavier end of the platform 14during the engagement of the shoulder 50 by the pin or member 52 of thesaid platform is positively prevented until the platform is again liftedout of the track depressions T by the sloping forward end walls T of thesaid depressions. The arrangement of the parts is such, furthermore,that the rack B shall have been swung into its ware-delivering positionbefore the power-transmitting platform n has been lifted out of thetrack depressions T, and the arm 36 at the outer end of its incline g isprovided with a rearward extension 46, whose outer side edge is arrangedparallel with the path of the bar G and is engaged by the roller hof thelever H during ICO ing end walls T of the said track depressions untilthe member 52 of the said platform has disengaged the shoulder 50.

To lock the rackB in its ware delivering or unloading position andretain the same until the jar or ware thereon has been taken from thesaid rack and to automatically unlock the said rack when the jar or warehas been removed from the rack,the following is provided: One of thearms 35 of the rack B (see Figs. 9, 11, 15, 16, and 17) is provided atits free end with a notch or recess 55, which extends vertically throughand longitudinally of the said arm and is open at its outer end. Thesaid arm at the outer side of the said recess is provided with anincline 56, the trend whereof is inwardly and forwardly toward the freeextremity of the said arm. The track T is provided with an upright latchL, which is pivoted at its lower end horizontally and transversely ofthe track, as at Z. The latch L is arranged, therefore, to swing in avertical plane and longitudinally of the track T. The latch L isprovided at its lower end, above its axis, with a forwardly-projectingarm 57, which is provided at its upper side and free end with an incline58, which slopes upwardly and for- Wardly and is arranged in the path ofa pin or laterally-projecting member ,with which the body portion 1* ofeach carriage 25 is provided. The latch L is provided also at its lowerend with a rearwardly-projecting arm 60, which carries a poise 62,normally resting upon an arm or bracket 63,which is rigid with andprojects laterally from the track T. The poise 62 acts to retaint-h'elatch L in its normal position, in which the incline 58 of the latch isarranged, as already indicated, in the path of the members 1* of thebody portions r of the carriages 25. The arrangement of the parts issuch that the incline 56 of the rack B during the swinging of the saidrack into its ware delivering or unloading position comes intoengagement with the latch L and swings the said latch forwardly againstthe action of the poise 62 until the recess 55 of the rack B has comeopposite the said latch, whereupon the latch will be swung rearwardly bythe action of the poise 62 into the said recess, and thereby lock thesaid rack in its said unloading position, The arrangement of the partsis such, furthermore, that the pin or member a" of the body portion 0'of each carriage 25 will during the propulsion of the said carriage notcome into engagement with the incline 58 of the latch-arm 57 until thejar or ware w has been removed from over the rack B, as shown in Figs.16 and 17, whereupon the said arm will be depressed by the passage ofthe said .pin or,

member 1* over the incline 58, so as to result in the swinging of thelatch L against the action of the poise 62 out of engagement with therecess 55.0f the rack, and obviously the said rack as soon as unlockedby the disengagement of the latch L from the said recess is swung by theaction of the weight 1 into its normal and ware-receiving position.

A yielding stop arranged to limit the roarward movement of the bar (irinto its normal position is provided and consists, preferably, of aspiral spring s, which is arranged longitudinally of and attached to thesaid bar and extends from within a recess 65, formed in the rear end ofthe bar a suitable distance beyond the said end of the bar, as shown inFigs. 8 and 11, and in the aforesaid position of the bar projects into arecess 66, formed in a lug 67, whichis formed upon and projects from thetrack T.
